b7cf773540 libexpr: warn when encountering IFD with warn-import-from-derivation
This is intended to be a softer version of
`allow-import-from-derivation`, allowing for users to only flag when IFD
is encountered rather than error out

By default, Lix allows you to import from a derivation, allowing building at evaluation time. With this option set to true, Lix will throw a warning when evaluating an expression that uses this feature, allowing users to know when their evaluation will requires any builds to take place.

This option has no effect when allow-import-from-derivation is false.
